Almost two decades after diagnosing the link rot phenomenon, and in spite of the universal character of the bit rot phenomenon, the need for reminding about these is still valid. This is because it appears that digital device users have become accustomed to them. The bit rot and link rot phenomena describe the inability to access specific contents or the inability to use specific digital resources. This paper aims to answer the question as to whether it is possible to eliminate the link rot and bit rot phenomena from the internet space.

The link rot and bit rot phenomena were characterised based on a review of various source materials, including the academic literature and internet materials.

The phenomena known as bit rot and link rot have already been well researched and described. Research has revealed the reasons for their occurrence, and also offered recommendations on how to minimise their occurrence. In the current digital ecosystem, however, it is not possible to completely eliminate the link rot and bit rot phenomena.

One can forecast that the link rot phenomenon will intensify and the internet resources will be even more unstable, because more and more new, highest-level domains which are purchased are emerging.

The study compares the phenomena of bit rot and link rot, even though they are usually considered separately. Moreover, it presents the terms of “digital bumps”, which cause “digital tsunami”.

This research aims to study the state of online resources cited in scholarly library and information science (LIS) journals which are ranked in ISI and available in the Emerald database in terms of accessibility and decay.

Four LIS journals published by Emerald were selected from Thomson Reuters' JCR. The journals' issues from 2005 to 2008 were downloaded directly from the publisher web site and checked in terms of decay and availability of individual cited URLs.

Original accessibility of studied online resources was 64 percent, which improved to 95 percent. The main adopted strategies that returned more results were using the Wayback Machine and Google, which revived online resources by 17 percent and 12 percent respectively.

To increase the rate of web citations accessibility, some recommendations, including avoiding long URLs, citing documents found in digital collections availability on the web, working through systematic checking of the web citations before publication, getting backup of cited information, using the more stable file formats and domains, and utilizing tools like WebCite^®‐enhanced reference and a digital object identifier (DOI^®) system are suggested.

A study which examines the accessibility and decay of web citations used by authors of articles published in ISI‐ranked LIS journals available in the Emerald database has not been already done. This paper can thus contribute to the knowledge of this field as well as quality of such literature for web content providers and publishers, authors and researchers.

The purpose of the present study is to identify the active and dead links of uniform resource locators (URLs) associated with web references and to compare the effectiveness of Chrome, Google and WayBack Machine in retrieving the dead URLs.

The web references of the Library Hi Tech from 2004 to 2008 were selected for analysis to fulfill the set objectives. The URLs were extracted from the articles to verify their accessibility in terms of persistence and decay. The URLs were then executed directly in the internet browser (Chrome), search engine (Google) and Internet Archive (WayBack Machine). The collected data were recorded in an excel file and presented in tables/diagrams for further analysis.

From the total of 1,083 web references, a maximum number was retrieved by the WayBack Machine (786; 72.6 per cent) followed by Google (501; 46.3 per cent) and the lowest by Chrome (402; 37.1 per cent). The study concludes that the WayBack Machine is more efficient, retrieves a maximum number of missing web citations and fulfills the mission of preservation of web sources to a larger extent.

A good number of studies have been conducted to analyze the persistence and decay of web-references; however, the present study is unique as it compared the dead URL retrieval effectiveness of internet explorer (Chrome), search engine giant (Google) and WayBack Machine of the Internet Archive.

The web references of a single journal, namely, Library Hi Tech, were analyzed for 5 years only. A major study across disciplines and sources may yield better results.

URL decay is becoming a major problem in the preservation and citation of web resources. The study has some healthy recommendations for authors, editors, publishers, librarians and web designers to improve the persistence of web references.

The aim of this paper is to scrutinize the accessibility and decay of web references (URLs) cited in five open access social sciences journals indexed by ISI.

After acquiring all the papers published by these journals during 2002‐2007, their web citations were extracted and analyzed from an accessibility point of view. Moreover, for initially missed citations complementary pathways such as using Internet Explorer and the Google search engine were employed.

The study revealed that at first check 73 per cent of URLs are accessible, while 27 per cent have disappeared. It is notable that the rate of accessibility increased to 89 per cent and the rate of decay decreased to 11 per cent after using complementary pathways. The “.net” domain, with an availability of 96 per cent (a decay of 4 per cent) has the greatest stability and persistence among all domains, while the most stable file format is PDF, with an availability of 93 per cent (a decay of 7 per cent).

Given the inevitable, destructive and progressing decay phenomenon in web citations, after estimating the extent of this decay for five journals using innovative and standard methods, this paper suggests recommendations for preventing it. The paper carries research value for web content providers, publishers, editors, authors and researchers.

The purpose of this study is to identify the persistence and decay of uniform resource locator (URLs) associated with Web references. The decaying of Web references is analyzed in relation to their age, domain, technical errors and error codes.

The Web references of the Journal of Informetrics were selected for analysis and interpretation to fulfill the set objectives. The references of all the scholarly articles, excluding editorials and reviews published in the Journal of Informetrics for five years from 2007 to 2011 were recorded in a text file. Later, the URLs were extracted from the articles to verify their accessibility in terms of persistence and decay. The collected data were then transferred into an excel file and tabulated for further analysis and interpretation using simple statistical techniques.

The results showed that of the total 7,409 citations retrieved from 221 articles, 358 citations (4.8%) were Web citations. These Web citations were assessed to find their persistence and decay. The results reveal that 115 (32.12%) Web references were missing or dead. The most common error associated with the missing Web citations was Error 404 Page not found, contributing 60% of the total missing citations, followed by 400 Bad Request Error (35.65%). The domain analysis of missing Web citations depicts that most of the missing URLs were associated with the .gov domain (40%), followed by .edu (29.58%) and .com (26.04%).

The Web references of a single journal, namely, Journal of Informetrics, were analyzed for five years, and hence, the generalization of findings needs to be cautioned.

The URL decay is becoming a major problem in the preservation and citation of the Web resources, and collaborative efforts are needed to reduce the decaying of URLs.

A good number of studies have been conducted to analyze the persistence and decay of Web references, as it is the hot topic of research across disciplines, and this study is a step further in the same direction.

The main purpose of the present study is to examine the availability and persistence of URL citations in two LIS open access journals. It also intended to calculate the half‐life period of URL citations cited in journal articles.

A total of 2,890 URL citations cited in 689 research articles published in LIS journals spanning a period of 14 years (1996‐2009) were extracted. In order to check the accessibility of URL citations, W3C link checker was used. After the initial check, inactive URL citations were listed. Domains and HTTP errors associated with inactive URL citations were identified for further analysis. The half‐life period was calculated using the formula t(h)=[t ln(0.5)]/[ln W(t)−ln W(0)].

The research findings indicated that 57.61 percent (397 of 689) of articles have URL citations and percentage of URL citations increased from 5.98 percent in 1996 to 27.79 percent in 2009. It was found that 26.08 percent of all citations were not accessible during the time of testing and the majority of errors were due to HTTP 404 error code (not found). The domains.net and.gov were more stable compared to the domains.com/.co,.org, and.edu. The half‐life was computed to be approximately 11.5 years, which compares favorably against earlier research works.

This is a comprehensive study on the availability and persistence of URL citations cited in LIS journals articles spanning a period of 14 years. The findings of the study will be helpful to authors, publishers and editorial staff to improve existing URL citation conventions and to promote URL use to ensure that URL citations are accessible in future.

The worldwide web is growing at an enormous speed and web citations are becoming very common in scholarly publications. However the major problem of web citation is its persistence since citations disappear over time, causing accessibility problems for readers. In this context the present study aims to investigate the availability of web citations and their persistence in Indian Library and Information Science literature. The study also aims to investigate types of link accessibility errors encountered, domains associated with missing web citations and the correlation between the path depth and missing web citations.

The web citations (URLs) from 350 articles published in Indian Association of Teachers in Library and Information Science (IATLIS) conference volume (2001‐2008) were extracted and then tested to determine the accessibility. The W3C Link Checker (http://validator.w3.org/checklink) was used to evaluate links associated with a cited web resource. This link checker tests a submitted web page for broken or non‐valid hypertext links and reports the types of HTTP messages encountered.

Results of the study show that the average citations per article have been increased substantially from 0.25 (in the year 2001) to 3.02 (in the year 2008). It also found that 45.61 per cent of citations are not accessible during the time of testing, and the majority of web citations show HTTP Error Code 404 (63.84 per cent). Web citations from the .org domain are found to have the highest failure rates (30.29 per cent) compared to .edu (21.49 per cent) and .com/.co (14.33 per cent) domains.

The researchers analysed 673 web citations from 350 articles published during 2001 to 2008 in IATLIS conference volumes. The study investigated the percentage of missing web citations and domains associated with missing web citations. The study suggests some possible solutions to improve web citation accessibility. This carries research value for web content providers, web authors and researchers in library and information science.

Discusses the means and methods of detecting timber decay and damp, briefly outlining the historic use of wood in the construction of dwellings and the role of the timber infestation surveyor. Details the process of a thorough inspection, both external and internal, suggesting that particular note should be taken of high earth or path levels, gaps round window frames, broken guttering, rainwater spillage, cracked renderings, missing slates, defective linings and blocked outlets in gutters, blocked airbricks and sagging roof tiles. Concentrates on fungal and insect damage and stresses the results of dampness. Discusses the importance of thoroughness.

Since the time of primitive man, timber has remained the most useful and versatile of all naturally available materials. Its obvious aesthetic value makes it irreplaceable in the manufacture of fine musical instruments, furniture and great works of sculpture, but its greatest use is in the construction of our dwellings. Whether used in its almost natural state to construct a forester's log cabin, or sliced up into convenient pieces to build most of the world's homes, it is unsurpassed for versatility, ease of working and mechanical strength.

The purpose of this paper is to know the rate of loss of online citations used as references in scholarly journals. It also indented to recover the vanished online citations using Wayback Machine and also to calculate the half-life period of online citations.

The study selected three journals published by Emerald publication. All 389 articles published in these three scholarly journals were selected. A total of 15,211 citations were extracted of which 13,281 were print citations and only 1,930 were online citations. The online citations so extracted were then tested to determine whether they were active or missing on the Web. W3C Link Checker was used to check the existence of online citations. The online citations which got HTTP error message while testing for its accessibility were then entered in to the search box of the Wayback Machine to recover vanished online citations.

Study found that only 12.69 percent (1,930 out of 15,211) citations were online citations and the percentage of online citations varied from a low of 9.41 in the year 2011 to high of 17.52 in the year 2009. Another notable finding of the research was that 30.98 percent of online citations were not accessible (vanished) and remaining 69.02 percent of online citations were still accessible (active). The HTTP 404 error message – “page not found” was the overwhelming message encountered and represented 62.98 percent of all HTTP error message. It was found that the Wayback Machine had archived only 48.33 percent of the vanished web pages, leaving 51.67 percent still unavailable. The half-life of online citations was increased from 5.40 years to 11.73 years after recovering the vanished online citations.

This is a systematic and in-depth study on recovery of vanished online citations cited in journals articles spanning a period of five years. The findings of the study will be helpful to researchers, authors, publishers, and editorial staff to recover vanishing online citations using Wayback Machine.
