Are Laser Printers Safe?

A study by Congrong He, Lidia Morawska, and Len Taplin in Environmental Science & Technology titled "Particle Emission Characteristics of Office Printers" raises questions about the safety of laser printers.

Here's an excerpt from a related Environmental Science & Technology news article:

When researchers in Australia discovered that particulate matter levels were five times higher during the workday inside a nonsmoking office building than outside near a freeway, they looked for indoor culprits. After testing more than 50 printers throughout the building, they found that particle emissions varied depending on the type and age of the printer. In one case, standing near a working printer was much like standing next to a cigarette smoker.

Here's an excerpt from a related Scientific American article:

When the researchers investigated emissions from all 62 printers in the entire six-story building, they found that 25 of them (40 percent) were emitting particles. Among those, 17 (27 percent) were "high emitters" (including HP LaserJet and HP Color LaserJet models, and one Toshiba Studio model), which caused the concentration of particles in the surrounding air to jump tenfold when just one page was printed. The majority of particles were ultrafine, or less than 0.1 micrometer in diameter.

"Because these particles are so small, there is a very high probability for these particles to deposit in the deepest alveoli in the lung. . .; from there they can enter the bloodstream," Morawska says. This could cause changes in blood properties that lead to cardiovascular disease, she notes. If the particles contain cancer-causing agents, exposure could also increase the risk of cancer, but Morawska says researchers did not test the chemical composition of the particles. The primary purpose of this study was to determine the concentration of ultrafine particles emitted by laser printers.

Web/Web 2.0 Tools and Techniques

Here’s a list of a few overviews of Web/Web 2.0 tools and techniques that developers may find useful.

Code4Lib Journal Established

The newly established Code4Lib Journal has issued a call for papers.

Here’s an excerpt from the call:

The Code4Lib Journal (C4LJ) will provide a forum to foster community and share information among those interested in the intersection of libraries, technology, and the future.

Submissions are currently being accepted for the first issue of this promising new journal. Please submit articles, abstracts, or proposals for articles to c4lj-articles@googlegroups.com (a private list read only by C4LJ editors) by Friday, August 31, 2007. Publication of the first issue is planned for late December 2007.

Possible topics for articles include, but are not limited to:

* Practical applications of library technology. Both actual and
hypothetical applications invited.
* Technology projects (failed, successful, proposed, or
in-progress), how they were done, and challenges faced
* Case studies
* Best practices
* Reviews
* Comparisons of third party software or libraries
* Analyses of library metadata for use with technology
* Project management and communication within the library environment
* Assessment and user studies . . . .

The goal of the journal is to promote professional communication by minimizing the barriers to publication. While articles in the journal should be of a high quality, they need not follow any formal structure or guidelines. Writers should aim for the middle ground between, on the one hand, blog or mailing-list posts, and, on the other hand, articles in traditional journals. . . .

The Journal will be electronic only, and at least initially, edited rather than refereed. . . .

Web/Web 2.0 Toolkits

Here’s a list of a few information-packed directories of Web/Web 2.0 tools that developers may find useful.

The IBM Gameframe

If you thought the era of big iron was dead, think again.

According to the New York Times, IBM is rolling out a "gameframe" that is "capable of permitting hundreds of thousands of computer users to interact in a three-dimensional simulated on-screen world described as a ‘metaverse.’"

Meanwhile, Sun is rolling out a video server that is "potentially powerful enough to transmit different standard video streams simultaneously to everyone watching TV in a city the size of New York."

LITA Next Generation Catalog Interest Group

LITA has formed the Next Generation Catalog Interest Group. There is also an associated mailing list.

Here is an excerpt from the LITA-L announcement:

NGCIG gives LITA a discussion space devoted to developments in the library catalog, its nature and scope, and its interfaces. It provides a forum for presentations and sharing of innovation in catalogs and discussion of future directions. Collaborations with other LITA interest groups, such as in the areas of emerging technologies and open source software, will provide opportunities for programming.

OCLC Openly Informatics Link Evaluator for Firefox

OCLC Openly Informatics has announced a free link checking plug-in for Firefox called Link Evaluator.

Here a brief description from the Link Evaluator page:

Link Evaluator is a Firefox extension designed to help users evaluate the availability of online resources linked to from a given Web page. When started, it automatically follows all links on the current page, and assesses the responses of each URL (link). . . .

After each link is checked, it is highlighted with a color based on the relative success of the result: green for fully successful, shades of yellow for partly successful, and red for unsuccessful.

It requires Mozilla Firefox version 1.5 (or later).
