ENGINEERING TOOLS, TIPS, AND LIMITATIONS Website for participants http://dl.lib.brown.edu/gateway/program.php?programid=403 Blog for engineering information newsletter http://blogs.brown.edu/project/libeng/ Compendex (http://www.engineeringvillage2.org/controller/servlet/Controller?EISESSION=1_83b1b111386d87c72a3bses4&CID=quickSearch&database=1 access only by Brown community) 1969-present, “Compendex® is the most comprehensive interdisciplinary engineering database in the world. Compendex references over 5,000 international engineering sources including journal, conference, and trade publications.” Platform for searching is called Engineering Village. A&I with links to full-text. Unique toolbox for advanced searching and refining has faceted searching which collects articles with the same indexing; can store queries for alerts, and history searching. Citations and abstracts with full-text access depending on Brown University Library’s subscriptions. Articles engineering-related. IEEE/IET Electronic Library Online (IEL) ( http://ieeexplore.ieee.org/Xplore/dynhome.jsp access only by Brown community) 1988- present, using the Xplore interface, the IEEE/IET Electronic Library provides libraries and researchers a single source to almost a third of the world's current electrical engineering and computer science literature. Resources include: IEEE journals, transactions, letters, and magazines from 1988 with select content back to 1952; IEEE conference proceedings from 1988 with select content back to 1953; IEEE standards from 1988; IET journals, letters, and magazines from 1988 and IEE conference proceedings from 1988. 15 concurrent users at a time. A&I with full-text. Unique toolbox includes searching full-text and history searching. Citations and abstracts with full-text access. Electronics-related journals, magazines, conferences, and standards. OTHER STM TOOLS ADS (http://adswww.harvard.edu/ ) The Smithsonian/NASA Astrophysics Data System maintains three bibliographic databases containing more than 5 million records: Astronomy and Astrophysics, Physics & Geophysics, and all ArXiv e-prints. The citations and abstracts in the databases are searched. A&I with some full-text searching and citation links to full-text. Query language found at HELP. Query form is atypical, requiring user to choose between simple and Boolean logic to combine terms. Unique toolbox for advanced searching includes querying of all three databases simultaneously and field searching. This free information service continues to add features including the scanning and searching of full-text articles in astronomy and astrophysics legacy journals with very comprehensive coverage often back to Volume 1. MyADS, for alerting by personal choice of keywords, supplements daily arXiv e-print list. Access to full-text refereed articles depends on Brown University Library’s subscriptions or open access archives. PubMED (http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?otool=brownlib&dr=abstract ) 1966–present; the National Library of Medicine’s MEDLINE search system, includes unique features such as phrase searching, automatic term mapping using a keyword thesaurus, history searching. A&I with links to full-text. Citations link to related articles and if appropriate, to genetic and molecular modeling data. PubMed has the ability to store searches for later automatic

updating. Citations and abstracts with full-text access depending on Brown University Library’s subscriptions or open access publications. Biomed focus SciFinder Scholar (http://www.brown.edu/Facilities/University_Library/eresources/edatabases/sfs.html access only by Brown community with computer client downloaded from CIS) 1894 – present, comprehensive database of chemical literature from CAS databases produced by Chemical Abstracts Service. It covers the full spectrum of chemistry-related information, including chemical structures, properties, biosequences, polymers, analysis, materials, and life sciences. Coverage includes journals, trade magazines, dissertations, patents, conferences, etc. To use, software must be downloaded from CIS onto each computer. 6 concurrent users at a time. Citations and abstracts with full-text access depending on Brown University Library’s subscriptions. Knovel Library Current, Collection of science and technology reference books and databases from major publishers. Many tables and graphs are interactive. Knovel’s “flagship” books are the Plastics Design Library Series, Perry’s Chemical Engineers Handbook, K-Essentials (7 free titles from print and Knovel-created composites), Lange’s Handbook of Chemistry, and a host of titles in mechanics & mechanical engineering featuring Mark’s Standard Handbook for Mechanical Engineers along with the ASME Boiler and Pressure vessel codes. Knovel’s toxicology offerings are quite comprehensive with 21 books. Popular books being the Dictionary of Substances and Their Effects, Sittig's Handbook of Toxic and Hazardous Chemicals and Carcinogens, Sax's Dangerous Properties of Industrial Materials, and, Patty's Toxicology and Industrial Hygiene. Knovel has recently partnered with the American Institute of Chemical Engineers to make available the many important books in the Center for Chemical Process Safety Guidelines Series. Lastly, Knovel has many of the important DoD Military Handbooks, including a fully interactive version of MIL-HDBK-5H: Metallic Materials and Elements for Aerospace Vehicle Structures. Functions include interactive Excel tables and Equation plotter tips – Each information source including Google has unique content, coverage, and

presentation of results/hits. Each information source including Google has a unique toolbox of advanced searching features including its Query Language.

Databases complied by algorithms – e.g. Google Scholar, Web of Science, Scirus Databases compiled by information specialists – SPIRES, IEL, SciFinder, PubMed

(subject search more powerful and focused than keyword because of assignment of standardized subjects/descriptors)

Multi-database searching one at a time is the only way to be assured of comprehensiveness.

Multi-database searching one at a time for a literature survey is essential. ADDENDUM Compendex Search query: nanotechnology; autostemming off; sort by Publication year

Check out: Search tips Help Sort by relevance (algorithm) or date Limit by document type, treatment type, languages, dates Autostemming off Browse indexes

Download citation to Refworks: Search history: Excellent functionality for improving recall and precision – get what you need as well as want.

IEL with IEEE Xplore search interface Basic search: nanotechnolgy Also can browse journals and conferences by name and ieee standards by a variety of navigations Help gives information on unique toolbox for searching

search is keyword in all fields including title, abstract not full-text view as citation or citation and abstract Search within results Brown subscription gives access to AbstractPlus and pdf

AbstractPlus has highlighted term(s), subject terms (controlled indexing that link to other articles in IEL), terms assigned that link, and author keywords that link, references (some linked) Author links to papers by same author in IEL Citation download requires extra steps for RefWorks and BibTex currently

Advanced search All fields + full-text of articles – broadest search possible but not very precise. Combine terms Limit results by publication, date range Organize display of results

Browse journals or conferences by keyword or title, and IEEE standards by keyword or number

History search with Boolean combinations and numbers of search lines tips - Sources of Other STM Information

Books (print & digital) Patents (FT searchable 1976- ) Gray literature (especially digital) Websites (authoritative and vetted)
