The Whole Earth Blazar Telescope (WEBT)
The WEB Telescope (WEBT) is a network of optical observers who in
concert have the capability to obtain continuous, high-temporal-density,
optical monitoring of blazars.
The Blazar Times
It is an electronic newsletter dedicated to research and refereed
publications on the BL Lac and blazar phenomena, observationally as well
as theoretically. The primary goal of the newsletter is to give easy and
rapid access to the latest results in blazar research.
Active
Galaxies Newsletter
This Newsletter is an electronic publication dedicated to the
observation and theory of active galaxies. It is intended to be used to
notify others in the field of recently accepted papers, conference
proceedings and dissertations, and also contains contains announcements
of jobs and conferences.
BLAZAR
Data Journal (Closed)

The X-Ray astronomy satellite SAX
homepage contains data archive of a selected list of SAX blazar.
There are informations on the future gamma-ray ASI mission
AGILE too.
Torino Astronomical Observatory
The site of the Torino Astronomical Observatory contains a research
section about the Blazar
Optical Monitoring and Extragalactic
Physics.
The Optical Monitoring Blazar List at Perugia Observatory
The list of blazar observed during the monitoring program (1994-now)
with the Automatic Imaging Telescope. Contains data, finding charts,
photometric data of comparision stars and light curves.
3C
273's Database by ISDC Geneve
This site gives access to most world wide observations of the quasar 3C
273 covering more than 40 years of measurements from the radio band to
gamma-rays.
Blazar Research at "La Sapienza" University - Rome .
Contain also the SCAE group Blazar
database.
Extragalactic X-ray Astronomy at Hamburger Sternwarte
X-ray astronomy became topic of research in Hamburg with the launch of
the ROSAT
satellite in 1990. A larger effort undertaken is the identification of
ROSAT sources on Schmidt plates of the Hamburg
Quasar Survey. Moreover they're working on the construction of a
complete well defined X-ray
selected sample of BL Lac objects

OSSE, EGRET observations. In particular the site contains the CGRO
Gamma-Ray Source Catalog .
GLAST Science Document and GLAST science at GSFC
Contain a section about the scientific topic about gamma-ray
observations of blazars performed by the next generation Gamma-ray Large
Area Space Telescope.
NED, NASA-IPAC Extragalactic Database
Contains more than 3 million of extragalactic objects measurements and
references. It's operated by the JPL, under contract with the NASA.
CDS Strasbourg
Database
Contains the Simbad, VizieR, Aladin, databases/services and other
resources (catalogues, nomenclature, bibliography etc.).
HEASARC AstroBrowse Service
This service developed by HEASARC
allows users to query hundreds of different catalogs and services
distributed around the world using a single simple interface.
Multimission STScI Archive
Level5 Knowledgebase for Extragalactic Astronomy
This service is supported in part by the NASA
and by the Carnegie
Institution of Washington (CIW), in conjunction with the NED.
It bring together in a single Web site (where copyrights allow) original
documents and reviews in html format and/or electronic links to articles
of current and lasting interest to cosmologists, particle physicists and
extragalactic astronomers. Contains data, catalogs, links, information
and an active
galaxies page.
