For full functionality this requires Internet Explorer 5 or above (or Netscape 6+ or Firefox 1+), Java Run-Time Environment 1.4.x up to 6.x, and Acrobat reader.
Access is by network (IP) address authentication, so if you are off campus you will need to investigate off-site (off-campus) access
Go to the handbook website (http://www.hbcpnetbase.com/).
The system is not wholly intuitive. Probably the most important feature of the home page is the link 'Substance/ Property Search' - this allows searching by structure, molecular formulas, registry numbers, property values, etc and is far more powerful than the 'Text Search' which only searches text. Alternatively, you can browse sections of the handbook by using the 'Table of Contents' on the home page.
Click on the link on the home page, and then you will be given the option to draw and search for a (1) chemical structure AND/OR (2) chemical properties (including name of substance, molecular formula, registry number, property value). If you want to search for (1) or (2) but not both at once, change AND to OR in the "Use Chemical Structure AND/OR Chemical Properties" command just above the Search button. The end result of the search will be a list of documents (corresponding to tables in the print version) in the handbook that have matching entries... see c below about using these results.
This searches the text only of the handbook by keyword. It will not find formulas, registry numbers, etc. Compound names can be used. The end result of the search will be a list of documents (corresponding to tables in the print version) in the handbook that have matching entries... see c below about using these results.
In most cases you will have a choice of Text (requires Acrobat Reader) or Table.
Clicking on TEXT will open the document as a PDF file that looks just like the printed table. After a 'Document Search' the hits are highlighted and you can use the 'Jumps to the next highlight' command in the Acrobat Reader. After a 'Structure/ Property Search' you need to use the 'Find' and 'Find again' commands in the Acrobat Reader.
Clicking on TABLE will open an interactive table version of the search results.
There is help on the system accessed through the 'Help Contents' tab on the left hand navigation.
