It should be a common feeling for many people to have access to the internet: if they want to see something, they want members; if they want to get a high-resolution picture, they have to pay for downloading; if they want to learn a little skill, the course costs hundreds of thousands. Fee thresholds are everywhere on the internet, often on an ad hoc basis, with dozens of members, idle after all, and worthless。
It's all over the internetFree resourcesWebsites, however, many of them contained advertisements, bullet windows, which accidentally downloaded bundles of software and even risk links and did not dare to light them. The nine sites we're sharing today are all regularPublic service platformsIt is free of charge and free of all costs, and it is safe to do so without a messy advertising window. Many are unaware of their existence and have been spending money on meeting staff and wasting money for nothing。
First of allLearning materialsClasses, suitable for students, working people, for literature and textbooks。
First, the national centre for philosophy social science documentation. This is an official documentation platform, where many periodicals, such as literature, social sciences, economics and history, can be read and downloaded directly, free of charge. It takes a few dollars to download a paper from a familiar documentation platform, and it costs a lot of money to look into it. This platform contains thousands of academic journals that are accessible without the need to register complex titles, and that can be used for writing papers, doing industry research and developing knowledge. It should be noted that the platform is dominated by social content and that there are relatively few scientific and technical literature available, which you can search for on demand。
Second, the national library reference consulting union. Many do not know that this platform is equivalent to a large public library online. It contains a large volume of electronic books, periodicals and newspaper materials, and many of the old books that are out of print on the market can be found here. It is used in a simple manner, and when documentation requirements are submitted, staff members send electronic copies through mailboxes, which are completely free of charge. It is very difficult to buy real books in order to find old teaching materials and industry materials, and there are likely to be gains to be made by retrieving them inside this platform。
Third, china digital science and technology. The site, which focuses on general content, includes graphics, short videos and audio courses covering astronomical, biological, physical and geographical fields. It would be appropriate for parents to look for generic materials for their children, or for adults to use debris time to learn a little bit about generic science. The content of the platform is officially produced and audited, and the knowledge points are accurate, and there will be no web-based rumours and rumours that can be used to avoid pits。
And then there's the material resource. A lot of friends who do graphics and clips are here every monthMaterials websiteMember fees have been spent, and the following can replace most fee-paying material stations。
Fourth, pixabay. This is a formal overseas material platform used by many of the country's creators, with pictures, illustrations, short videos, background music, all of which are free commercial authorizations. Simply put, after downloading, there is no need to worry about copyright complaints, either for self-media mapping or short video background material. Many new people from the media have stepped on the pit, simply saving pictures from the web and finally receiving copyright claims, using material from this platform to avoid this risk. The only thing that needs to be noted is that the search results are enriched by the use of english keywords when searching。
Fifth, pecels. Similar to the pixabay above, the main video and photographic material was played with a high degree of clarity. Its live video is of high quality, and many of the short films of landscapes, cities, daily scenes are basically 1080 ps. When a headline, short video is required, it is not necessary to go to a monthly meeting person on a paid-for-material site and download it directly here。
Sixth, the font is in the world (free of charge). A lot of people who make posters and graphics are easy to ignore. Many of the good-looking fonts on the internet are not readily available for commercial purposes, and once posted on a media platform, they can easily be notified of violations. The site is dedicated to a free commercial font area, where the fonts can be used directly free of charge, which is downloaded with a careful look at the authorization note, giving preference to the formula “free commercial” and avoiding the individual non-commercial fonts。
It is followed by a tool-based web site, which is a light online tool, without downloading and installing software to save software members ' expenses。
Seventh, ilovePDF. In day-to-day work, PDF processing is a high-frequency requirement that converts format, compresses sizes, splits, adds watermarks, many PDF software with high-level functionality. The online site, which provides all the underlying PDF processing functions free of charge, has a direct uploading of files at the end of the web page, which is then downloaded without the need to install a swollen client inside the computer. Free versions have individual document size limits, and ordinary office documents are generally available and suitable for temporary emergency work。
Eighth, cornvertio. This is an online format conversion tool that supports the conversion of videos, audio, documents and pictures into several dozen formats. For example, video transliteration, photo transfer to PDF, conversion to each other's audio formats, many small formats, and local software can hardly find a decodator that can be quickly converted using this online tool. When editing daily, problems with format incompatibility are often encountered, and this site can save many member fees for conversion software。
Ninth, the popular science board of the chinese knowledge network. The first impression is that many people are paying for downloading papers, but many are ignoring the fact that there is a science-wide section dedicated to the general public. It contains a number of easy-to-understand trade readings, health studies, life studies, not obscure professional papers, which can be read directly without paying permission. Some authoritative health knowledge, industry common sense are routinely sought and can be retrieved from here without attempting to sketch out the fragments of rumours in the video。
Finally, we would like to focus on two additional reminders. These sites are themselves formal public platforms and are free of charge and are relatively secure because they do not decipher websites or steal payment resources. But when you're on the internet, you must recognize the official domain names, and there's a lot of fake sites on the internet with similar names, advertising and tied software, which can be easily confused。
There is also a margin of error to make clear that these free platforms are not everything. For example, the documentation platform, not all papers are available; the material site, too, will have limited popular style material. A website should not be expected to address all needs, but rather as a complementary tool. Many people spend thousands of dollars a year on a variety of memberships, materials and software, and learn to use these free formal platforms to save money slowly。
The internet has grown to date, and there are a number of official public digital resources in the country, although it is poorly publicized and largely unknown to ordinary people. We are accustomed to meeting directly when we encounter demand, and instead neglect these free public service resources. When used, you are also required to comply with the platform's user protocols and not be able to repackage and sell the downloaded material, respecting the rules governing the use of content。
Are there any of the nine websites you shared today that you used before? Or do you know other official, non-advertising, free public websites, and you're welcome to share comments and communicate with each other in the comment area? If you find the content useful, you can ask for attention and then continue to share such practical online tools。
