有些论文的Full text只提供给subscribers，普通用户不能下载。这个时候如果在本校或者其他开放的libraries也下不到的话，只能发邮件索取了。据我的感受，老外一般都很热情，也很愿意与你沟通交流（国人的话就看RP了）。如果不涉及到商业机密和版权问题，一般都会成功。下面有2篇信件原文，是我从互联网上找的，大家参考。
第一篇是索要论文
Dear Prof. Carlos Antonio
I am writing to request your assistance. I am a doctor student and study at Northwestern Science and Technology University of Agriculture and Forestry, my research focus on hypoxia stress. I searched one of your papers: “The metabolic response of plants to oxygen deficiency” is published at Brazilian Journal of Plant Physiology. I am very interested in you paper, but I can not read full-text content, would you mind sending your full-text content by E-mail
I am looking forward for your kind reply early. Thank you for your assistance.
With kind regardsSincerely yours

第二篇是索取某一解答的详细推导和作者最近的其他论文
我的邮件：
Dear Dr. Sagaseta,
I am a Ph.D student of Zhejiang University at China. Recently, I have read one of your articles, titled “Consolidation around stone columns. Influence of column deformation” in “Internation Journal for Numerical and Analytical Methods in Geomechanics”.I got many new ideas from your article. For me, your work is quite innovative. However, there are some jumps in the derivations of the solutions presented in Table 1 of your paper(i.e.,General elastic solution. Stresses and Strains for any load pa and excess pore pressure u) and it is difficult for me to understand these results. I wonder if you would consider sending me the detailed derivation of the solutions presented in Table 1 in a seperate Word file. In addtion, I would be grateful if you can sent me some papers regarding your recently research about the subject of your present paper by Email.Respectfully yours,

Dear Mr. Lu,
Thank you very much for your interest in our recent publication. I’m the other author of the paper, which was basically the core of my PhD thesis. In my thesis, the solution is derived in detail, unfortunately, it’s written in Spanish, so please, give me a couple of weeks to translate this part of the thesis and I will gratefully send it to you.I’ve read also part of your work with Prof. Xie, e.g. a paper in Computer and Geotechnics, in the field of consolidation of composite materials. I’ve got also some ideas, because you apply your consolidation derivation to the Han and Ye’s solution, and I think it could be also applied to the solution that we’ve published in the Int. J. Num. and Analyt. Met. in Geom. So, please, feel free to ask further questions and I am open to any kind of collaboration.
Regarding to other papers, I don’t know now of any other that could be of interest for you. We’ve got another paper in the 2nd IWGSS (www.iwgss.org), but it’s basically a summary ot the journal paper.
We keep in touch.
If I happen not to send you the derivation in a couple of weeks, please remind me it.
With kind regards,Jorge

1. Dear Dr David Botstein,
I am a post-doctoral researcher in Liu's lab at XX University.
I have recently read your paper "Directly fishing out subtle mutations in genomic DNA with histidine-tagged Thermus thermophilus MutS", which appeared in "Mutation Research". I am interested in trying your approach for detecting mutations in yeast.
I was wondering if you would be kind enough to send me the pETTthMutS plasmid reported in your paper.

Kind regards,
Liu2. I'd appreciate a file (pdf) containing yourr article: Mutat Res. 2004 Mar 22;547(1-2):41-7. Directly fishing out subtle mutations in genomic DNA with histidine-tagged Thermus thermophilus MutS. Wang J, Liu J.
Thank you in advance
Best wishes

3. Dear Dr. Liu,
I read with interest the abstract of your article in Mutation Research, "Directly fishing out subtle mutations in genomic DNA with histidine-tagged Thermus thermophilus MutS." Unfortunately, our library does not subscribe to Mutation Research. I would be most appreciative if you could please send me a .doc or .pdf file of the article by e-mail.
Thank you,
