I would greatly appreciate feedback on your experiences with the Dictionary of Organic Compounds.
We have recently upgraded our computers and find that we cannot reload and use the 1995 DOC ver.3:1cd-roms purchased from Chapman and Hall. We had not purchased any updates.

CRC, the new owner of the electronic version cannot help us. Our last print version was 1982, so we are faced with a big need to either repurchase or find alternative sources for this information.

Since we have already been burnt by paying big money for the cd's which we thought we would have forever, we are hesitant to repurchase them again. CRC tells us that the print will not be updated from the current version. Our choices appear to be buy cd's at $3000 and keep buying updates at the same cost, buy web access at $4000 per year ad infinitum, or find additional sources. Our only search option is academic access to STN.

Any helpful hints?

Thanks in advance,

We think that there is indeed no need for DOC on CD-ROM when you have access to Beilstein CrossFire - I think we just cannot afford such redundancy.

We still keep an older print edition of DOC at hand for "quick reference" of clients that want this, but will not update that either.

Let's not do away with the DOC quite yet. Certainly large institutions which have Beilstein can rely on an old copy. However, many smaller institutions will still need this product because they cannot afford campus wide access to Beilstein. Also, I, for one, feel the DOC is an excellent tool for the undergraduate researcher as well - keeping them away from the more exotic materials that may not be available or affordable. The DOC is also a great ready reference source. My guess is, unless you have
CrossFire running, you may be able to find your compound more quickly in DOC et. al, than getting into the database. I have also been told that the DOC focus is very different than the Beilstein. Where DOC focuses on compounds of use, Beilstein focuses on new information and research figures. And let us not forget the CA RN issue.

To: CHMINF-L@LISTSERV.INDIANA.EDU

Let me add my 2 cents. While Beilstein is much larger than DOC, DOC is still extremely useful. We use the DOC for an undergrad class and have up to 30 simultaneous users using 2 copies of the CHCD that are mounted on an NT CD-ROM tower.

The DOC interface takes much less time to learn how to use for simple searches than Crossfire. DOC is a also highly edited set that contains a key set of references, including review papers and citations to articles in treatises. I do not believe it is possible to limit by doc type to review papers in Beilstein, although a kw search of the abstract field that contains 'review' would limit results. I don't believe treatises are included as sources in Beilstein.

Derivatives listed in DOC are sometimes much more "mainstream" than ones appearing in Beilstein, esp. for undergrad audiences. Beilstein seems to have a narrower definition for derivatives than DOC. In order to find some derivatives it is necessary to do a reaction search as the derivative of interest isn't included in the chemical derivative field.

For natural products, Beilstein currently has about 107,000 compounds classified as being isolated from a natural product. DNP (Dict. Natural Products) has over 120,000 cmpds. So, the DNP most likely contains cmpds not included in Beilstein.

The CHCD is updated every six months and does include a time- out feature. That's why the cdrom from original note sent out no longer works. Not sure if you can cancel and retain a working copy of the CHCD or DOC.

I may be wrong, but there is no risk to try: Install the Linux Red Hat (or other kind of Linux)
on your computers in place of Windows 9x! This system is more stabile and more efficient
than Windows 9x It can emulate DOS (and even Windows 3.1).
I am sure that all your 1995 DOC ver.3:1 CD-ROM's will become readable. You will save much, very much money. Linux is free. But you must be in contact with a Linux guru. Linux is difficult.

The other possibility would be to "re-upgrade" one or two of your computers with the old system.

I wish you success!

If I remember correctly, Chapman and Hall changed their initial licence policy when upon cancellation of updates to CHCD one would loose all they subscribed to until then. The updated version stated that institution has to pay a cancellation fee in order to retain access to what they paid for. Institutions could also resubscribe within one year and pay just an update. After more than one year break in cancellation, they would have to repurchase the whole thing again.
Th following is message posted to this list in 1994 after a lot of discussions about pricing arrangements of Chapman and Hall.
Chapman & Hall is pleased to announce that we now have some
exciting new solutions to licencing queries that have been
raised on our range of CD-ROM products on the Chem Info
list over the last few months.

Please contact Alexa Dugan in the Uk on 44 (0)71 865 0066 or
Jacqui Macia in the US on 301 699 7777

Unfortunately, I don't have exact wording of "new exiting solutions" in hand.

Thanks to everyone for their help with DOC.

We had purchased a perpetual license to DOC on CD-Rom, so timing out was not the problem. ( This may have been one of the "new Options Zdena mentioned). The perpetual license came on a separate disc, and is needed to reinstall the software. If anyone else purchased the perpetual license, please be sure that you hang on to this disc.

DOC v.3.1 is also not compatible with Windows NT, which is what we had just installed. We will have to down-grade one pc to run DOC.

I also agree the DOC is the best choice for our undergrads. Although our faculty is clamoring for it we cannot , alas, afford Crossfire, so we will stick with DOC for another year or two, and hope there are some changes in pricing.

Thanks to Fiona MacDonald at Chapman Hall/CRC for helping to clarify this problem for me.
