Welcome to the UCL Library Services subject guide to chemistry. These pages are maintained by Lynne Meehan, your subject librarian for chemistry. They provide links to resources of relevance to chemistry. The content is regularly revised and feedback or suggestions are welcomed.
The printed collections in UCL Library Services are described below. There is also information about:
WISE for Built Environment, Engineering, Maths and Physical Sciences
WISE is a comprehensive, step-by-step online guide to finding and using information effectively. Go to http://www.ucl.ac.uk/moodle, and log in with your UCL userid and password. Click on WISE and select Built Environment, Engineering, Maths and Physical Sciences to start the course (If WISE does not appear in your list of courses click on “All courses” in the top left menu then select WISE and register yourself on the course.) Help with WISE.
Regular training sessions on electronic library resources are held in the DMS
Watson Teaching Cluster. For dates and times see Information
Skills Training. Individual training sessions on specific databases
and other electronic resources can be arranged
For further information or to arrange an individual training session contact

The Chemistry collection is
on the 3rd floor of the Science Library, housed in the
DMS Watson Building. There may be relevant material elsewhere in the
The Library has its own classification scheme for arranging books on the shelves.
A typical classmark for a book will consist of the name of the subject (indicating
a section of the Library) followed by letters and numbers indicating its classified
position on the shelves within that section. For instance:
CHEMISTRY F 72 IMA for Lathanides in organic synthesis by Tsuneo Imamoto
(where Chemistry is the collection; F 72 the classified position within the collection
and IMA the first three letters of the author's surname).
The CHEMISTRY collection is divided into several sections. Some important
ones are as follows:
CHEMISTRY C - analytical chemistry
CHEMISTRY D - physical chemistry
CHEMISTRY F - inorganic chemistry
CHEMISTRY H - organic chemistry
CHEMISTRY M - medicinal chemistry
Some of the other sections of the Library you might need are:
PHYSICS (Science Library, 3rd floor)
ENGINEERING (Science Library, 4th floor)
COMPUTER SCIENCE (Science Library, 3rd floor)
MEDICAL SCIENCES (Science Library, 2nd floor)
Use Explore to find the exact class mark (shelf location) of a book.
The library holds both print and electronic journals (periodicals). Journals cannot be borrowed but may be photocopied, subject to copyright. Chemistry journals that we keep on site are in the PHYSICAL SCIENCES Pers section on the third floor of the Science Library. Older journals and those which are available electronically are held in the library Store. Journal volumes held in the library store can be requested via the Store Request Form.
Use Explore to search for journals the library has access to (select UCL journals in the resource list). Explore also allows you to search for articles within some journals (select Journals articles). Contents of journals can also be searched via indexes and abstracts.

Material in electronic form is available to registered members of UCL. To access these resources, users are advised to navigate to material using the links from the Library Services website. If you are off-site, you will be prompted for your UCL userid and password. For more information about this visit the
for electronic library resource users section of the Library Services website.
Indexes, abstracts and e-books
The Library subscribes to a number of bibliographic and full-text databases, of which the following
might be particularly useful:
SciFinder gives access to the Chemical Abstracts Service
databases of chemical literature (back to 1907), structures and reactions.
The first time you use the web version of SciFinder, you will need to register your details via a UCL networked computer. You need to provide your name, university email address, choose a username and password and answer a security question, entering any other information is voluntary. Once you have completed the registration form you will receive an email from CAS with the terms and conditions of use. You will need to click on the link provided to complete your registration.
To use SciFinder web off-site you must connect to the university network via Remote WTS.
Once registered for SciFinder web you can log into your account from your smartphone via scifindermobile.org/ whether on, or off-site and access the mobile friendly SciFinder mobile interface. SciFinder mobile does not include all the functionality of the PC version.
Reaxys is a web-based search and retrieval system for chemical compounds, bibliographic data and chemical reactions. It is built to support chemists in their daily work with focused and relevant information in chemistry. Includes the content of the three CrossFire databases: Beilstein, Gmelin and Patent Chemistry Database. The Reaxys Training Centre has links to a variety of documents and videos on how to use Reaxys .
Web of Science indexes over 6000 science journals from 1981 onwards. You can follow a number of online tutorials in various languages on the Web of Knowledge website by clicking here. You will need a browser running Flash Version 8 or higher to view these tutorials.
Scopus is a comprehensive scientific, medical, technical and social science
database containing references to journal articles, conference
proceedings, trade publications, book series and web resources. For further information see the online tutorials at SCOPUS.
PubMed indexes biomedical literature, including all data from the Medline database from the National Center for Biotechnology Information (NCBI) at the US National Library of Medicine (NLM). Medline is the premier database for journal articles in the health sciences. For further information see the online tutorials provided on the PubMed website.
an interactive database and ebook provider containing full-text science and engineering publications
and including tables, graphs and equations which can be manipulated and exported. Useful for chemical and physical property data.
For a complete list of databases available at UCL go to http://www.ucl.ac.uk/Library/database.
A range of journal titles are available electronically to registered members of UCL.
- To look for a specific title, go to the alphabetical list on the Library's web pages at
You will also find details of the access arrangements for each title.
For further information you can consult the Library leaflet on How
to find printed & electronic journals & journal articles.
For information about exam papers, and access to all undergraduate and postgraduate papers for the last 5 years up to 2010, go to http://www.ucl.ac.uk/Library/exam.shtml.
Online papers for Chemistry are available via this link.
Paper copies of exam papers for the current year for all Main and Science Library subjects are shelved in the Photocopying Room of the Main Library. Older papers are available in printed format and are kept in Stores. These can be requested by clicking here.

ChEMBL - ChEMBL is a database of bioactive drug-like small molecules, it
contains 2-D structures, calculated properties (e.g. logP, Molecular
Weight, Lipinski Parameters, etc.) and abstracted bioactivities (e.g.
binding constants, pharmacology and ADMET data). The data
is abstracted and curated from the primary scientific literature, and
cover a significant fraction of the SAR and discovery of modern drugs.
Additional data on clinical progress of compounds is being integrated
into ChEMBL at the current time.
Chemical Database Service - provides free access for eligible users to databases on Crystal strucutres, spectroscopy and themophysical properties.

A user may enter compound identifiers such as Chemical Name, CAS Registry Number, Molecular Formula, Classification Code, Locator Code, and Structure or Substructure. New searchable features include search and display by Toxicity indicators such as Median Lethal Dose (LD50), by Physical/Chemical Properties such as LogP, and by Molecular Weight.
