To find entries in the database:

	Choose the type of lookup via the "Search Type" pull-down menu.

	If looking up by just a Title, Author, Note, or Year, enter
	the desired title, author, note, or year in the input box.

	If a biblook-style regular expression lookup is desired,
	choose Regular Expression via the "Search Type" pull-down
	menu.  Then type in a regular expression in the input box.

	Hit the GO button, or press return.

	See examples below.

	Note:	The default is to clear results before each search.
		(See info on CLEAR/APPEND mode changes below)


To save the results:

	Click on the SAVE button, and enter the desired filename
	into the popup window.


To change CLEAR/APPEND modes:

	TkBiblook's default behavior is to CLEAR the results before
	each search.  The CLEAR/APPEND button is a toggle button
	which toggles between CLEAR and APPEND modes.  If you are
	in CLEAR mode and wish to APPEND the results of the next
	lookup, press the CLEAR/APPEND button, and TkBiblook will
	be in APPEND mode.  The button will change its appearance
	to an APPEND button.  Pressing the CLEAR/APPEND button
	again toggles back to CLEAR mode.


To quit TkBiblook:

	Press the QUIT button.


Information on regular expressions supported in TkBiblook/biblook:

	[not] <field> <words>
		  Find the entries containing the given words in
		  any field with a prefix matching the <field>
		  argument.  For example, "a" matches both "author"
		  and "address", and "au" matches "author" only.
		  If the <field> argument is "-" (or any string
		  with no letters or numbers), match any field.

		  If "not" appears before the <field>, the sense
		  of the search is reversed.  The symbols "~" and
		  "!" can be used in place of "not".

		  Each word is a contiguous sequence of letters
		  and digits.  Case is ignored; accents should be
		  omitted; apostrophes are not required.  Single
		  characters and a few common words are also ignored.
		  Any word ending with an asterisk is treated as
		  a prefix.  Thus, "point*" matches "point",
		  "points", "pointer", etc.

	and [not] <field> <words>

	or [not] <field> <words>
		  Intersect (resp. union) the results of the given
		  search with the previous search.  Several of
		  these commands may be combined on a single line.
		  Commands are handled in the order in which they
		  appear; there is no pre- cedence.  Unlike other
		  commands, and like "not", these must be spelled
		  out completely.  "&" can be used in place of
		  "and", and "|" can be used in place of "or".


Example:

	The following example is a regular expression taken from
	the biblook documentation and finds all STOC papers cowritten
	by Erdo's without "Voronoi diagrams" in the title:

	 _________________________________________________________________
RegExp 	[ b stoc* | b symp* theory comp* & au erdos & ~t voronoi diagrams ]
	 -----------------------------------------------------------------

	Another less complex example might be

	 _________________________________________________________________
RegExp	[ title diagram and year 1991                                     ]
	 -----------------------------------------------------------------
	
	This is an example of doing a lookup via just a title

	 _________________________________________________________________
Title	[ diagram                                                         ]
	 -----------------------------------------------------------------


Misc information:

     ';' are not allowed in the regular expression search string.
