The Law School Admission Council administers the Law School Admission Test (LSAT) and the Law School Data Assembly Service (LSDAS), which collects information for law schools. (For information about the LSAT, click here.)
Always follow the procedures listed for the law schools you will apply to. In general, law schools expect applicants to use the LSDAS service for collecting letters of recommendation and transcripts. For information about LSDAS procedure, see the LSAC web page: www.lsac.org.
Remember that while LSDAS allows online as well as mail registration, some materials, e.g., official transcripts, must still be sent as hard copy by the Registrar.
