The National Center for Biotechnology Information Entrez Direct (EDirect) software facilitates programmatic access to numerous biomedical, chemical, and literature databases from within a Unix terminal. EDirect has traditionally been used for command line access to NCBI data within the fields of computational biology and bioinformatics. This…

Developing skills for searching the patent literature is an essential element of chemical information literacy programs at the university level. The present article creates awareness of patents as a rich source of chemical information. Patent classification is introduced as a key-component in comprehensive search strategies. The free Espacenet…

Critical thinking and analytical problem-solving skills in research involves using different search strategies. A proposed concept for an "Imploded Boolean Search" combines three unique identifiable field types to perform a search: keyword(s), numerical value(s), and a chemical structure or reaction. The object of this type of search is…

A science librarian in the laboratory can become a "point of access" for database instruction and provide a learning opportunity for students to develop their information literacy skills. A case study describes how a librarian in an organic chemistry laboratory helps the class run smoothly and identifies the science librarian as an ally and a…

Describes a chemistry course titled "Writing for Chemists", a junior-level course required of all chemistry and biochemistry majors at California State University (CSU) that covers all of the sections for writing both primary and secondary papers in the chemical sciences as well as the process of literature searching in both computer databases and…

Describes student involvement in conducting literature searches using the online literature retrieval methods of the Lockheed DIALOG system as a part of a junior-level Introduction to Independent Study Course. Outlines the teaching methods, presenting a set of practice questions with answers and discussing the progressive building of good study…

Describes some support programs and materials that facilitate preparation of an effective and inexpensive classroom program on online searching of the chemical literature. Presents more than 20 databases by type of database and subject area. Discusses practice files and overall cost. (MVL)

Focuses on the CAS ONLINE database, the Registry File which consists of substance names, Registry numbers and characteristics, and actual structural representations. Presents several examples covering most typical problems a chemist faces daily. (Author/MVL)

Describes a program developed to expose college chemistry students to some of the more modern information retrieval tools, as computerized online databases. Following classroom lectures and discussions, students individually develop a search statement relevant to their own research needs and run it in the Chemical Abstracts files. (BT)
