Dear Colleague You are receiving this message because you are an author for a chapter in the Handbook of Star Forming Regions. We are finally at the point of having all the chapters completed, and so we can move into the final brief phase of each reviewing and updating our chapters one last time. Below I send various comments. The Handbook is now at 1800 pages, and while it has been possible for me to read and comment on everything as the chapters trickled in, it will be impossible to check the final submissions in detail, so please read this message in its entirety, it contains important details for a successful completion process. 1) The Handbook will be printed by the ASP as a special publication, not as part of their conference series, and it will appear as two volumes for the northern and the southern sky. I have arranged with the ASP to receive the Handbook by May 19, and at a minimum two weeks are needed to compile and check the two volumes, prepare Tables of Contents and Indices, etc., so the latest I can receive your revised and updated chapters will be MONDAY MAY 5. Please do not submit beyond that deadline and, if at all possible, send your chapter early, so I can frontload the work. 2) An amazing amount of work has gone into this project by everyone involved. The Handbook will be a truly unique source of information, and every attempt has been made to reach a very high level of detail and completeness. In order to avoid to mar the book with a serious omission or any error, I ask you all to read critically through your chapters with fresh eyes, and work with the lead author to incorporate any changes or new results. Also check that your chapter is camera ready, if you have problems just write me. 3) You can at any given time see the status of the book at the Handbook web site at http://www.ifa.hawaii.edu/users/reipurth/handbook/index.html login: handbook, pswd: author where you can download your own as well as all other chapters. Please keep this URL confidential. 4) More than one hundred authors are involved in this project, and together we constitute a significant fraction of the observational astronomers working on star formation. I would therefore like to ask each of you to read at least one other chapter, preferably one in which you have expertise and/or new results, and contact the author with your comments, if any. 5) Many of you have used and referred to the Dobashi et al. (2005) atlas of dark clouds. After many discussions with the IAU Nomenclature Committee and SIMBAD, it has turned out that we cannot use the designation DoH favored by Dobashi, instead these clouds have to be named TGU. When you review your chapters, pls change DoH to TGU everywhere. 6) I have talked individually to each of you about the use of color figures in the book, which we can do if we pay $50 per page that uses color. The ASP has set up a web site where it is possible to arrange payment, so when we have the final layout of the book, I will inform each lead author about the charges, and each team can make the arrangements they prefer. 7) The ASP has been very helpful at every step of this process. Since they are a non-profit organization they can sell our book at a far lower price than for-profit publishers. The ASP has also agreed to allow authors to buy discounted copies, that is, at $50 per volume plus postage. A web site is being set up on which orders can be made, and I will write you about that when the book has been submitted. Meanwhile, we can of course download electronic copies from the Handbook website, which is continuously updated. 8) Those of you who would like to make preprints available on astro-ph or elsewhere are welcome to do so. I will be reviewing each chapter for layout issues, update the slug, and make other cosmetic changes. So if possible, please wait until the day the Handbook is submitted, so we can be sure that your preprint is truly the final version. with best wishes and thanks again for your support of this project Bo Reipurth
