The Library of Congress posts information about all bills and resolutions under consideration by both houses of Congress at THIS ADDRESS.
It is easiest to find legislation by bill number, such as S4 (for Senate bills) or HR1543 (for House bills). The bill number will always be given in any communication from the PAC about pending legislation. But you can also search by bill title or sponsoring member of Congress or by key words (for example: visa waiver, Obamacare, etc.).
Unfortunately, the results of such a search are temporary – you cannot save nor forward to anyone the links the search returns, because they expire and become invalid. Instead, you must repeat the search each time you want to see the information.
