At the beginning of the 1950s, G. Shajn and V. Gase fulfilled an imaging survey of the Milky Way in the hydrogen Ha emission line with 640-mm and 450-mm (F : 1.4) astrographs.
Before this survey, only about 80 emission nebulae were known. Their catalogue has listed 301 objects
(Gase 1955),
the majority of which were new diffuse emission nebulae.
The “Atlas of diffuse gaseous nebulae” by G. Shajn and V. Gase was one of the most popular surveys at the time before the completion of the Palomar Sky Survey
(Shajn 1952 [S-1952]).
Short reviews of the emission nebulae studies by G. Shajn and V. Gase are made by S. Pikelner (
1957,
1957a ) and V. Pronik (
1995 ).
To search for exciting stars of emission nebulae new catalogues of stars of early spectral type were needed. G. Shajn ( 1955 ) described the research plan for this study: "Partly for that purpose spectroscopic observations of stars brighter than 12m.2, by means of a 400 mm camera equipped with a 410 mm prism with angle 6°.9 are being carried out at the Simeiz Observatory. Star magnitudes, color indices, and color excesses are also being determined, mainly in the regions with emission nebulae". A short summary of the Shajn's Plan was given by G. Shajn and V. Gase ( 1951 ). This plan was later transformed to the Plan of the Galaxy’s structure studies (Kolesnik 1995).
2. The Shajn's Plan realization
The Shajn's Plan was fulfilled by 12 researchers. Seven researchers worked at the Crimean Astrophysical Observatory: E. Brodskaya, R. Ikhsanov, I. Kopylov, L. Metik, I. Pronik, P. Shajn, G. Sharapova. The remaining researchers were from various regions of the Soviet Union: A. Alksnis from Riga, N. Grigorieva from Moscow, A. Numerova from Leningrad, R. Raznik from Ulyanovsk, V. Straizys from Vilnius. Stars of different spectral types were studied in 13 sky regions near of 10° x 10° along the Milky Way. The observations data for all regions were obtained in the Simeiz and Nauchny with 170-mm and 400-mm astrographs. The detailed references may be found in the review by I. Pronik ( 2005 ).
3. The results publication of Shajn's Plan and digitization of the catalogues
Before beginning of the work on the analysis of results from Shajn’s Plane we executed expert operation as published catalogues are presented in modern database, interacting with IVO tools. In table 1 are presented a general characteristics of the studied regions and basic statistics for explored stars. The determination of the table columns: 1 – is a number of the region (Nr); 2, 3 – are right ascension (a) and declination (d) at the epoch 1950.0; 4, 5 – are galactic longitude (l) and latitude (b); 6 – is the size of the region in square degrees (A); 7 – is the number of studied stars (N); 8 – is the number of the O - B (A) stars (n); 9 – is the spectral classes hot (n) - stars (Sp); 10 – is a number of stars in SIMBAD (SI); 11 – basic references in the SOA/NASA ADS (B); 12 - catalogues in CrAVO databases (D).

* Contains a catalog of the 1953IzKry..10..120K [K-1953].
To continue analyze the data from Plane, we created the digitized version of the catalogues from print copies. Working on a digitized version of catalogues we understood that it should be in the formats similar to the representation of articles in the SAO/NASA ADS. The first priority in creating a digital version of catalogues is the addition of ADS titles of missing articles in order to eliminate discrepancies between the actual numbers of publications and those that are presented in the ADS. Next step - the list of objects and their characteristic, which is presented in catalogues. More detailed information about digitized articles from “Izvestiya of CrAO” (with included a catalogues from Shajn’s Plane) were described in articles by Bondar' ( 2013 ) and Shlyapnikov ( 2007, 2015 ).
4. The Shajn's Plan plate archive
Common information about archive of CrAO and main characteristics of individual plates from the Milky Way collection were performed in the united computer readable forms (Bondar' 2007). One form contains information about a telescopes (for more informations see "Instruments") and the other form appears plate parameters - coordinates of its center, exposure, emulsion, filter, sensitive (pg, pv), size (deg.), storage, time of observation (date, Julian date, local and sidereal time) and name of astronomer who made this observation (for more informations see "Observations").
Data files for direct and spectral plates are saved in ’dBASEIII+’ format and sorted in ascending of right ascension. Copies of these files submitted to the Wide-Field Plate Database (WFPDB). To request information about the plate it should be define coordinates of its center and size. Centers of plates for the epoch 1950.0 and description of the collection in detail are given in Bondar' ( 1999, 2006 ).
The current status of the archive data and observations with possibility of the access with applications of the IVOA is presented in sections of the "Observation" and "Catalogues".
